ATI's new family of graphics processors is finally born. It took the company a couple of years to develop Shader Model 3.0 graphics architecture and several month of re-spinning the chips to deliver products that run at nearly extreme clock-speeds. Let's find, what the RADEON X1800 XT, 1800 XL, 1600 XT and 1300 PRO are capable of!

Pixel Shader Performance

8 pixel processors of GeForce 6600 working at 300MHz prove almost as efficient as 4 pixel processors of RADEON X1300 PRO working at twice as high frequency. The only exception is PS 2.0 4 Registers shader, in all other cases the performance of these two products is identical.

All in all, we observe certain parity between RADEON X1300 PRO and GeForce 6600. However, just like in the previous case the last three shaders using dynamic branching and working within the version 3.0 shader model demonstrate ATI’s indisputable victory.

Thanks to incredibly high clock frequency, RADEON X1300 PRO outperforms all the competitors, including RADEON X700 and GeForce 6600.
